LBTZ-25 Polymer Cement Waterproof Coating Dispersion Mixer (Manual Lifting, Automatic Three-Stage Mixing)

Description

Product Introduction

Our company has newly developed a key piece of equipment for dispersing polymer‑cement waterproof coatings in laboratory settings, capable of fully programmable, multi‑stage speed control. Its design is sleek, compact, and refined, featuring a user‑friendly interface that meets the operational needs of laboratory personnel. This product boasts low noise, reliable operation, smooth speed regulation, and ease of use, making it ideal for research and production facilities across heavy industry, light industry, chemical processing, pharmaceuticals, and science‑education sectors.

Reference standard:

This cement‑based waterproof coating disperser is specifically designed for mixing polymer‑cement waterproof coating samples and preparing coating films. Its overall performance complies with the national standard GB/T 23445‑2025 “Polymer‑Cement Waterproof Coatings,” making it suitable for sample preparation and testing in relevant material laboratories. In accordance with clause 6.3.1.3 of GB/T 23445‑202, the disperser operates at a speed of 0 r/min to 2000 r/min; the diameter of the stirring impeller (e.g., a four‑blade propeller) should ideally be 1/2 to 2/3 of the inner diameter of the mixing vessel, with a compatible vessel capacity of approximately 1 L. During testing, the device automatically stirs at 200 r/min to 500 r/min for 1 to 2 minutes, during which powdered materials are slowly added to the liquid phase. The speed is then increased to 700 r/min to 1200 r/min, and stirring continues for 3 to 5 minutes until a uniform consistency is achieved. Finally, the speed is reduced to 100 r/min to 200 r/min, and stirring is maintained for an additional 2 minutes before concluding the process.

Key Features

1. Automatic three-stage constant-speed setting and timed stirring, rigorously aligned with standard test procedures, ensuring highly standardized sample preparation.

2. Equipped with a high-power motor, it delivers ample torque, ensuring uniform mixing and blending of materials.

3. Both the stirring paddle and the mixing vessel can be quickly exchanged, enabling multi‑purpose operation and meeting a variety of experimental requirements.

Function Key Description

1. ON/OFF: Power switch

2. Switch selection key

Press this key to toggle between selecting speed (rpm) and time (min), cycling sequentially from top to bottom and left to right.

3. START/STOP: Start/Stop button

Note: When the first time interval is set to “000,” the device will not operate. Setting the time to “----” activates the always-on operating mode.

4. Up key: In stop mode, when using the selection switch to set the speed (rpm) or time (min), pressing the up key increases the value.

5. Down Arrow Key: In stop‑mode, when using the selector switch to set the speed (rpm) or time (min), pressing this key decreases the value.
